GUIDE FOR CONCRETE-FORMS.

To all whom it may concern:

Be it known that we, ALLEN D. WHIPPLE and FRIrs CHRISTIANSEN, citizensof the United States, and residents of Milwaukee, in the county ofMilwaukee and State of Wisconsin, have invented new and usefulImprovements in Guides for Concrete- Forms, of which the following is adescription, reference being had to the accompanying drawings, which area part of this specification.

This invention has for its object to provide a guide for sheet metalforms used in concrete building construction to produce the molds inwhich the concrete is placed for forming walls and the like, the purposethereof being to secure a proper alinement of the forms and avoid thezigzag arrangement which is liable tobe taken by the forms when theirclamping means alone are relied upon for holding them in position.

With the above and other objects in view the invention consists in theguide for concrete forms as herein claimed, and all equivalents.

Referring to the accompanying drawings in which like characters ofreference indicate the same parts in the different views: Figure 1 is aplan view of a guide for concrete forms constructed in accordance withthis invention as applied in use for holding the sheet metal plates orconcrete forms in proper alinement; Fig. 2 is a side elevation thereof;Fig. 3 is a detail plan view thereof; and, Fig. 4: is a transversesectional view thereof.

In these drawings 10 indicates the guide member which is of angle-ironconstruction, as best seen in Fig. 4 and which becomes a straight-edgewhen applied to the upper edges of a set of sheet metal plates orconcrete forms 11 which are detachably connected together to form themold for the wall. These sheet metal forms 11 are provided with frames12 of angle-iron con struction and the flanges of each form or moldsection are provided with suitable clamping means 13 for clampingtogether the abutting flanges of the adjacent frames 12, as shown inFig. 3, and is as long as convenient for handling, so that each of theguides thus engages the abutting flanges of a number of the sheet metalforms. The horizontal face of the guide is provided at intervals withhook members 14 which are slightly arched to reach over the upperSpecification of Letters Patent.

edges of the concrete forms and engage their inner faces as shown inFig. 4. It is by means of this hook of the guide member 10 with theconcrete forms that the guide member is held in place and the distancebetween the depending portion of the hook members 14: and the uprightportion of the guide member 10 is just suflicient'to receive theconcrete forms between them without material play so that the forms arefirmly held by the hook members in their engagement with thestraight-edge and are therefore maintained in accurate alinement.

As a convenience for locking the guide in place, it may be provided atmtervals with turn buttons 15 in the form of flat sheet metal stripspivotally mounted on the top face of the guide member and adapted toproject beyond the upright face of the guide member when turned to oneposition and engage beneath the top flange of the frame of the forms.When the guide is thus locked in position, there is no danger of itsbeing accidentally disturbed and the true alinement of the forms isassured. The guide need only be applied to the forms on one side of themold, the forms on the other side of the mold being tied in parallelrelation thereto by means of tie rods 16 which have pins 17 projectingfrom them to enter openings in the flanges of the forms. When it isdesired to remove the guide for building up another tier of forms, theturn buttons 15 are swung out from beneath the flanges of the forms andthe guide may then be lifted and laid to one side until replaced uponthe new tier of forms.

By means of this invention the accurate alinement of the concrete forms,which is necessary to produce a straight wall, may be quickly and easilymade and the forms, when clamped thereto, will remain in their properalinement.

What we claim as new and desire to secure by Letters Patent is:

1. A guide for concrete forms, compris ing a straight-edge for engagingthe forms on one side thereof, and straight edge suspending hooksextending from the straightedge for passing over the upper edges of theforms and engaging their opposite sides for holding them in suchengagement with the straight edge.

2. A guide for concrete forms, comprising an angle-iron guide member,and guide member suspending means connected therewith for engaging theupper edges of con crete forms and holding them in engagement with theguide member.

3. A guide for flanged concrete forms,

comprising a straight-edge adapted to en-,

gage concrete forms on one side thereof, straight edge suspending hookson the straight-edge to pass over the upper edges of the concrete formsand engage the other side thereof'for holding said concrete forms insuch engagement with the straigl1t-edge, and turn buttons on thestraight-edge for I engaging beneath the flanges of the concrete formsto lock the guide in place.

4. A guide for flanged concrete forms, comprising a guide member ofangle-iron construction, arched guide member suspending means connectedtherewith for engaging the upper edges of concrete forms and holdingthem in engagement with the guide member, and turn buttons on theguidemember adapted to engage beneath the flanges of the concrete forms.

5. A guide for concrete forms, comprising a straight-edge adapted toengage the concrete forms on one side thereof, straight edge suspendinghooks on the straight-edge extending over the concrete forms and engag-ALLEN D. VVHIPPLE. FRITS CHRISTIANSEN,
